    Abstract

    To increase the durability of antibacterial coating on cotton and polymeric substrates, surface initiated grafting polymer brushes are introduced onto the substrates surface to bridge copper nanoparticles coatings and substrate. The morphologies of the composites consisting of the copper nanoparticles and polymer brushes were characterized with scanning electron microscopy (SEM). It was found that copper nanoparticles were uniformly and firmly distributed on the surfaces of the substrates by the polymer brushes, meanwhile, the reinforced concrete-like strutrues were formed in the composite materials. The substrates coated by the copper nanoparticles showed the efficient antibacterial activity against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) even after washing by 30 cycles. The copper nanoparticles were tethered on the substrates by the strong chemical bonds, which led to the excellent washable fitness and durability. The change of the phase structure of the copper was
    analyzed to investigate the release mechanism of copper ions.
